Comprehensive Python library for astronomy and astrophysics. This skill should be used when working with astronomical data including celestial coordinates, physical units, FITS files, cosmological calculations, time systems, tables, world coordinate systems (WCS), and astronomical data analysis. Use when tasks involve coordinate transformations, unit conversions, FITS file manipulation, cosmological distance calculations, time scale conversions, or astronomical data processing.

一个用于天文学和天体物理学的综合性Python库。在处理天文数据时使用该技能，包括天体坐标、物理单位、FITS文件、宇宙学计算、时间系统、表格、天球坐标系统（WCS）和天文数据分析。当任务涉及坐标变换、单位转换、FITS文件操作、宇宙学距离计算、时间尺度转换或天文数据处理时使用。
